1

whats a typical patient history who has melanoacanthoma

Rapid onset and growth Buccal mucosa most common site • Dark-brown or black pigmentation • Flat or slightly raised Predilection for black females • 3rd to 4th decades

2

Whats the etiology of melanoacanthoma

unknown. its considered a reactive lesion

3

how do you tx melanoacanthoma

• Incisional biopsy to confirm diagnosis • No further treatment is necessary • May spontaneously regress due to biopsy

4

what are the types of nevi

intramucosal, compound junctional

5

whats a intramucosal nevi

nevus found in the epithelial tissues

6

what is a compound nevus

found in epidermis and dermis

7

what is a junctional nevus

one found in-between epithelial and dermal tissues

8

where due blue nevi tend to occur orally

on the palate,

9

why are blue nevi blue

tyndall effect (physics) the cells tend to be deeper in the connective tissue and epithelial tissue above it reflect the blue light.

10

18

what can oral storage weber mimic

pyogenic granuloma

19

what is the ideal tx for peripheral osseous fibroma and peripheral giant cell granuloma

excise down to periosteum, then sc/rp to remove inciting irritant

20

what are names of benign peripheral nerve sheath tumors
